Nest 🐦

Use your filesystem as a nested data store!

Modules

nest

Example

use nest::{Error, Store, Value};
use serde_json::json;
use std::convert::TryInto;

fn main() -> Result<(), Error> {
    // what is the root path to your data store?
    let root = "./example-data";
    // describe how your data store will map to the filesystem
    let schema = json!({
        // refers to a directory: ./example-data/hello/
        "hello": {
            // refers to a file: ./example-data/hello/world.json
            "world": "json"
        }
    })
    .try_into()?;

    let store = Store::new(root, schema);

    // get `nest` key from `./example-data/hello/world.json` file
    let value = store.get(&["hello", "world", "nest"])?;
    println!("value: {:?} == 🐣", value);

    // set `nest` key in `./example-data/hello/world.json` file
    let next_value = &Value::String("🐥".into());
    store.set(&["hello", "world", "nest"], next_value)?;

    // get a sub-store for data within `./example-data/hello/world.json
    let sub = store.sub(&["hello", "world"])?;
    let value = sub.get(&["nest"])?;
    println!("value: {:?} == 🐥", value);

    // try to get a value that doesn't map to the schema
    if let Err(err) = store.get(&["invalid", "path"]) {
        println!("err: {}", err);
    };

    Ok(())
}

Example

Given example-data:

tree -a example-data
# example-data
# ├── hello
# │   └── world.json
# └── .nest.json
#
# 1 directory, 2 files

cat example-data/.nest.json
# {
#   "hello": {
#     "world": "json"
#   }
# }

cat example-data/hello/world.json
# {
#   "nest": "🐣"
# }
cd example-data

nest get 'hello/world'
# {
#   "nest": "🐣"
# }

nest set 'hello/world/nest' '"🐥"'

nest get 'hello'
# {
#   "world": {
#     "nest": "🐥"
#   }
# }
